RADIATOR.

Application filed December T aZZ whom it may concern:

Be it known that we, Hum-1m L. W'Hrrt- LAW, a citizen of the Dominion of Canada, a resident of the county of St. Louis, State of Missouri. and lVAL'rnn Gr. VoLLM'nn. a citizen of the United States, a resident of the city of St. Louis. State of Missouri, have in vented certain new and useful Improvements in Radiators, of which the following 1 is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This inventionrelates to improvements in radiators, one of the objects being to produce an efficient combination boiler and radiator having a combustion chamber containing a burner, said combustion chamber being provided with a movable end wall whereby the length of said combustion chamber may be regulated.

With the foregoing and other objects in view, the invention comprises the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown the preferred embodiment of the invention. However, it is to be understood that the invention comprehends changes, variations and modifications which come within the scope of the claims hereunto appended. I

Fig. I is a front elevation, partly in section, illustrating a radiator embodying the features of this invention.

Fig. II is a fragmentary cross section of the lower portion of my improved radiator showing the adjustable end wall. of the com bustion chamber.

Fig. III is a section on line IIIIII of Fig. II.

The radiator shown in the drawings comprises end sections A and B provided with legs 1 whereby all of the intermediate sections are supported above the floor. A designates what we will term boiler sections, arranged in a horizontal row and alined with heat-radiating sections B. Upper and lower tie rods 2 pass through all of the sections, said rods having nuts at their ends which may be adjusted to securely unite the sections.

All of these sections are hollow and their upper ends are connected by means of tapering nipples 3 (Fig. I) which place all of the 1, 1922. Serial No. 604,326.

sections in communication with each other, excepting the end section B, which lies far thest from the boiler sections A, and which does not have its upper end in direct com munication with the next adjacent section. a plug, or closure l. being used at this point (Fig. To establish communication lrctween the lower ends of all of the sections, tapering nipples 4. are used, these nipples forming partof a continuous water-passage way wherein water is returned from the sec- Eons B and B to the boiler sections A and Each boiler section has a recess open at the bottom of the section, and the several. recesses are in horizontal alinement with -each other to produce an elongated combustion chamber (3, said chamber having top and side walls formed partly by hollowportions of the sections and partly by mating ribs 5 extending from the sides of the section. In addition to this, each boiler section A is provided with a tubular water-receivinubridge 6 extending across the combustion chamber and communicating with the fluid passageways in the boiler sections. The several bridges 6 are connected together through the medium of the nipples 4. An angular flue 7, formed integral with one of the boiler sections, extends from the top of the tornbustion chamber at a point approximately midway between the ends thereof, and leads to one side of the radiator. Immediately below the entrance to the flue, one of tho tubular bridges has a tapering upstanding battle rib 8 to deflect the oppositely moving prod ucts of combustion to the flue.

The end walls of the combustion chamber are formed partly by a web 9 on the and section A and partly by a plate 10 which can be removed and located in different positions to vary the length of the combustion chamher. The plate 10 has rounded lugs 11 at ts upper edge adapted to closely fit in spares between the tubular bridges 6 in the boiler sections, or between similar bridges 6 in the heat-radiating sections. These lugs can also fit between one of the bridges 6 and one of the bridges 6, as shown in Fig. I.

The lower portions of the hollow sections are provided with notches 12 to receive portions of the plate 10. To remove this plate, it is lifted from the notches 12 and then tilted while its upper edge is withdrawn bustion chamber and causing an from the tubular bridges. To permit the lifting movement, the upper edge of plate is notched at 13 (Fig. II) so as to clear the projecting rib around the nipple i. The lugs 11 at the upper edge of said plate are adapted to fit between any of the adjoining tubular bridges 6 or 6, and the lower portions of this plate are adapted to enter any aair of the oppositely disposed notches 12.

The bottom of the combustion chamber 6 is open to receive a gas burner 14 which lies within the lower portion or the combustion chamber and extends approximately from end to end thereof. By having the combustion chamber open at the bottom, the burner can bedropped onto the floor below the radi vator and it can be readily placed in the cont bustion chamber. The open bottom also serves as an outlet for burned matches dropped in lighting the burner and falling to the floor instead of collecting in the cornodor. Furthermore, the secondary air for combustion freely enters the open bottom of the com.-

" bustion chamber at all points throughout the length of the burner.

Primary air enters through a return bend '15 (Fig. I) at the outer end of the burner. The gas-controllingmeans comprises a manually operated valve 18 on a housing 19 and a safety Valve (Fig. I) is applied to the end section A.

The outer end of the burner 14- is support:- ed by a screw-threaded nipple 26 and a threaded union 27 whereby gas is conducted from the'housing 19 to the passageway 16. To support the burner at different elevations relative to the combustion chamber, along-er orshorter nipple can be substituted for the nipple 26. For the-same reason the plate 10 at the inner end of the combustion chamber has two holes28 formed one above'the" other to receive an extension 29 on the inner end of the burner: two vertical walls and ltc'an be ad usted vertically without varying the width of the.

The burner lies between tor wherethe nipples 3 establish communica- 53 tion between all of the sections, and the air is expelled through an air valve I) on the heat-radiating section B farthest from the boiler, the upper end of this section being closed by the nipple 3 which serves a plug to prevent direct communication betweeen this upper end and the next adjacent section.

We claim:

1. In a sectional radiator, a row of hollow 05 sections having a combustion chamber in their lower ends, said combustion chamber having an end wall ad ustable longitudinally of the combustion chamber to Vary the length thereof with respect to the length 01" 7 the radiator, and a burner in said combustion chamber.

:2. In a sectional radiator, a row of 1101- low sections each having'a n opening in its lower end, the openings being alined with 753 each other to form a combustion chamber, 7 an end wall for said combustion chamber ad'- justable from one of said sections to another to vary-the length of the combustion chainher with respect to the length of the radiso ator and a gas burner in said combustion chamber.

3. In a sectional radiator, a row of hollow sections each having an opening in its lower end, the openings being alined with each other to tornra combustion chamber, aiiend' wall for said combustion chamber adjustable from one of said s'ection-s to anotherto va rl the length of the combustion chamber, said sections having separated portioasforming 9Q recesses wherein said end wall isremovably" interlocked with the sections, and a gas burner arranged in saidcombustionchamber and having one of its ends supported by said end wall.
